The rivalry intensified through their online interactions, with Tetsuka questioning why Aoki had blocked him on social media in 2024. The verbal sparring escalated when Tetsuka used his own YouTube channel to issue a direct challenge to the veteran grappler, telling him “Don’t run away.”
Aoki brings legendary credentials to this grudge match. The 42-year-old Tokyo native holds a 49-11 record built over more than two decades competing at the sport’s highest level. His submission game has produced 32 finishes via tapout across his career, establishing him as one of MMA’s most accomplished grapplers.
Since joining ONE Championship in 2012, the former lightweight champion has secured 15 promotional victories with 13 finishes. His recent form shows no signs of decline despite his age. Aoki submitted Eduard Folayang in 53 seconds at ONE 172 in March, following his rear-naked choke victory over John Lineker at ONE 165.
The victory over Tetsuka would give Aoki his third consecutive MMA win and the historic 50th victory of his career. That milestone would further cement his status among the sport’s all-time great submission specialists.
Tetsuka provides a legitimate challenge despite recent setbacks. The 35-year-old former Pancrase Welterweight Champion drops to lightweight specifically for this matchup. His ONE Championship record includes six victories with five finishes, validating his reputation as a dangerous finisher.
His recent form has been inconsistent. Tetsuka rode a five-fight winning streak before consecutive losses to Isi Fitikefu and Zhang Lipeng halted his momentum. The back-to-back defeats created urgency for a statement victory that would reestablish his credibility among Japan’s elite fighters.
The weight class adjustment adds another variable to the matchup. Tetsuka has competed primarily at welterweight during his ONE Championship tenure, making his lightweight debut against one of the division’s most accomplished athletes a significant test of his versatility.
The tactical dynamics favor Aoki’s grappling expertise against Tetsuka’s finishing instincts. Both fighters have demonstrated the ability to end contests decisively throughout their careers, suggesting the judges may not be needed. The personal animosity built through their social media exchanges adds intensity to a matchup that already carries significant pride for both Japanese competitors.
